Physical exercise boosts your brain power in 20 minutes, helps stop brain shrinkage
Scientists have been linking the benefits of physical exercise to brain health for many years, but new research is making it clear that the two aren't just simply related; rather, it is THE relationship.

PRMT7 preserves satellite cell regenerative capacity
PRMT7 is required for muscle stem cell self-renewal and regenerative capacity in vivo. PRMT7 deletion causes senescence of activated muscle stem cells. This entry into senescence is associated with persistent expression of p21.

Breakthrough in generating embryonic cells that are critical for human health
Neural crest cells arise early in the development of vertebrates, migrate extensively through the embryo, and differentiate to give rise to a wide array of diverse derivatives. Their contributions include a large proportion of our peripheral nerves, the melanocytes that provide skin color and protection from damaging UV light, as well as many different cell types in our face, including muscle, bone, cartilage and tooth-forming cells.

Timing of expression of the core clock gene Bmal1 influences its effects on aging and survival
Ironically, antiaging product advertisements often promise to “slow down the clock.” But abolishing the circadian clock—for example, by knocking out Bmal1, a core clock gene—accelerates aging and shortens the life span in mice. As a result, Bmal1 knockout mice often serve as a model system in studies of the role of circadian rhythms in the aging process. Now Yang et al. show that the developmental timing of Bmal1 expression influences the circadian clock’s effects on aging and survival.

Drug prevents age related brain changes in rats

Drug prevents age related brain changes in rats
As brain cells age they lose the fibers that receive neural impulses, a change that may underlie cognitive decline. Researchers at the University of California, Irvine recently found a way to reverse this process in rats. The study was published Feb. 3, 2016 in The Journal of Neuroscience. Researchers caution that more studies are needed, but the findings shed light on the mechanisms of cognitive decline and identify potential strategies to stem it.

Study Reveals Proteins Most Associated With Aging And Age-Related Diseases
Researchers have revealed a list of proteins most associated with aging and age-related disease including Alzheimer's. The team has found that short and highly charged proteins are most vulnerable to oxidation, which damages proteins in aging cells.
